system/gdm: Removed (not functional with CK2)

I looked around in the gdm code and don't see anything obvious
that would make it not work with CK2, and google turned up nothing
useful. I did notice that PCLinuxOS is using gdm-2.20.11 as well,
but aside from a special dbus config file (which I tried here with
no change to behavior), I don't see anything special that they do.
They use PAM though, so maybe that makes a difference.

These days, I don't even use gdm any more - I'm on xdm with
alienBOB's config (slightly modified) from his livecd work. The
only things that users might miss are a session chooser (change
$HOME.xinitrc instead) and switching users (I don't like that
anyway), so good riddance to this one.

-Subject: Handle new crypt() behavior in glibc 2.17+
-
-Starting with glibc 2.17 (eglibc 2.17), crypt() fails with EINVAL
-(w/ NULL return) if the salt violates specifications. Additionally,
-on FIPS-140 enabled Linux systems, DES/MD5-encrypted passwords
-passed to crypt() fail with EPERM (w/ NULL return).
-
-If using glibc's crypt(), check return value to avoid a possible
-NULL pointer dereference.
-
-Note: gdm 2.20.11 is the last version that support non-PAM 
-      authentication which is why it is the latest stable
-      maintained for Slackware Linux via slackbuilds.org.
